Re-publish routes between IGRP, VPN, and OSPF

During the re-release of routes between IGRP, OSPF, and OSPF, I don't know what I am busy with. I 've been writing this article for a week. I don't know how to take the test in March /, main contents of this experiment: 1) Release of the classless and classless networks; 2) re-release between various routing protocols. (3) The S0/0 of R1 and R2 are used as follows: the S0/1 of R2 and the S0/0 of R3 are OSPF, And the loopback port of R3 is IGRP.
